与执行a.out文件（C++）发行的MacOS塞拉利昂10.12.1

Question

我刚刚更新到塞拉利昂，似乎我的编译器土崩瓦解出于某种原因。

我写的代码更新之前工作得很好，所以我敢肯定它根本不是问题，但现在它只是不工作什么那么当我尝试执行它。

这里是输出。

$ g++ source.cpp 
$ ./a.out 
dyld: mach-o, but built for simulator (not macOS) 
Abort trap: 6 

运行G ++具有详细用于@NulledPointer

可以有多种选择：

• 尝试安装缺少的工具（如果有的话）使用xcode-select --install和尝试编译。如果失败，
• 尝试运行gcc -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk source.cpp。这显然假设你已经在该位置安装了SDK。替换那里存在的任何位置。
